It looks better because the box is stretched in that direction (so it will foreshorten more because the other side is much farther away) and because of the viewer's perspective.
That being said, it's still a bit weird. Try rotating the page looking at it from another angle. Next time don't draw the lines so parallel if some part of the box is going to have a considerable foreshortening.
EDIT: this last tip only applies when drawing boxes in 3 point perspective, obviously.
